| Popis: | Category: Ankle Arthritis; Ankle Introduction/Purpose: There is limited evidence regarding risk factors for medial malleolar fractures after total ankle arthroplasty (TAA). A previous study showed that patients with medial pain following TAA had significantly thinner ( 4 weeks postoperatively (cases) were identified through radiologic assessment (radiograph, CT, or MRI) and matched to a control group of 129 patients. Radiographic evaluation included pre- and post-TAA tibial coronal alignment, postoperative medial malleolar width at the tibial component, and prophylactic screw fixation. Demographics and radiographic variables were compared between cohorts using the Mann-Whitney U test for continuous variables and Pearson Chi-square for categorical variables. Logistic regression was used to investigate the association of medial malleolar stress fractures with gender, coronal tibial implant size, postoperative coronal alignment, prophylactic screw fixation, and medial malleolar width using odds ratios (OR), and standard error (SE). Results: Of 838 TAAs, 2.51% sustained a postoperative medial malleolar fracture (n = 21). Of these, 13/21 (61.9%) required reoperation: internal fixation (12) and TAA revision (1). Mean (SD) medial malleolar width was significantly smaller in the fracture cohort (8.62 mm [1.63]) than in controls (11.78mm [1.75]), P |
